Sales are everywhere. Sale on shoes, bags, shirts, gadgets and everything. Malls and shops use this technique to attract buyers, but you know what?  Do you think you've been discounted a higher price than ordinary? No. Instead of saving 20%, you spend 80% on things you dont really need. This is not economical and most of us are easily lured to it. This is what i hate about people. When there's useless trending items on sale, they buy immediately even on credit cards but if bitcoin drops, they talk negative about it. Normal mindset wants to get temporary attention. Not permanent comfort.
